' IMPROVEMENT IN HEATlNG-STOVES.

Specification forming part of Letters Patent No. 176,998, dated May2,1876; app ication file March 20, 1876 To all whom 't't may concern Beit known that I, DAVID C. PROCTOR, of Peoria, in the county of Peoriaand State of Illinois, have invented a new and useful-Im- I provement inHeating-Stoves, which improvement is fully set forth in the followingspecification. s

My improvements relate, particularly, to that class of stoves, designedfor burning wood, known as The Todd Stove, and they consist,essentially, in a'certain novel construc- 'tion and arrangement of partsfor increasing combustion and the radiation of heat, and regulating themat will, as hereinafter fully explained.

' In the drawing, Figure 1 is a longitudinal I vertical section, Fig. 2atransverse vertical section through line a: a: of Fig. I, Fig. 3 a

top view, and Fig. .4 a horizontal section, of a stove embodying myimprovements.

The main body A, which'consists of a hori-f zontal barrel,ellipti'cal orcircular in section, is divided, near its closed rear end, into a smallor smoke-draft chamber, B, and a large or -fire chamber, 0, by atransverse vertical dia-f phragm or partition, D. This diaphragm has anopening through it near the top, closed with an adjustable valve, E, forpermitting, when desired, a direct draft from the fire chamber into thepipe b, and especially when kindling the fire, and another opening, d,through the base of the diaphragm, below the plane of the horizontalfloor F of the fire chamber, between which floor and the bottom of, thestovesuficient space, F is left to act as a fiue. The floor F, uponwhich rests the burning fuel, joins the diaphragm D tightly at its rearend, and the dead-air lining or double wall 0 of the stove at its sides,and extends forward within a short distance of the stovedoor G,sufficient space, a, being left between its edge and the door to permitthe free entrance of the escaping products of combustion into the spaceF beneath the floor, and thence into the smokedraft chamber B, saidspace a being thus made to act as a divingflue. A raised ledge or guard,f, formed at the front edge of the floor, prevents the escape over it ofashes and coals, and the con-' sequent choking of the diving-flue. Theheated currents, when directed by the closing of the valve E, are causedto pass to the front edge, and beneath the floor F, along'it from frontto rear, heating the entire bottom of the stove, and escaping throughthe opening d in the base of the diaphragm up into the smokedraftchamber B, where it heats the entire dle of the diaphragm within a short"distance of the floor or fire-bed F, giving free space for the passageof air. Just below the valve-'- openingE in the top of the diaphragm,the

flue I is divided into diagonal branches it, running upward 011 eachside of the opening, and communicating at the top, through the wall ofthe stove, with the outer air, by openings closed with adjustable slidesa 6. When it is desired. to increase the combustion of the fuel, theseslides are opened, admitting a draft of air from the outside, which, asit passes down between thediaphragm and the wall'of the flue, becomeshighly heated therefrom, and passes fromthe open lower end of the fluethrough the fire, from rear to front of the fire-chamber, being thusdrawn when valve E is closed, thence back through from front to rear,under the floor, and up through the smoke-draft chamber at the back, thewhole surface of the stove being thus thoroughly heated. When the'valveE is opened, the products of combustion escape directly into the pipe,as before stated. The slides e 0 can, of course, be regulated to admitthe air in any desired quantity into the draft-pipe I.

It is evident that the draft-pipe I may be divided into two pipes, andmade to pass down at each side of the inner surface of the stovewalls,terminating nearly on a level with the fire-bed, or constructed in anyother suitable manner, so that the essential idea bepreis'ervetL-namely, that of a top draft, con1- municating with the firein the interior of the body of the stove at the rear of thefire-chamber. An essential advantage afforded by the position of thetop-draft descending-flue is, that it occupies no appreciable'space inthe fire-chamber, as it forms a part of the back wall of suchchamber, sothat the hot air entering the fire-chamber thereby enables the of thefire-chamber, Iamenabled to form the entrance of the diving'fliie bythus shortening the floor itself, and to place the entrance of thediving-flue at the end of the firechamber opposite to that at which thedraftpipe 1 is arranged and, by reason of the arrangement'of thedraft-pipe at the inner or rear end of the fire-chamber, I am enabled tomaintain and regulate a brisk fire with the door and hearth of the stoveentirely closed, I and thereby to dispense with all front draft andregisters for regulating the same. For the purpose of cleaning the stoveI. provide an ilSll-1)3.l1,1 of the ordinary kind, which, extending infront of the stove, forms a continuation of the bottom or diving fine.

I claim as new and of my invention- 1. The combination, in thestove-body A, of the diaphragm D, provided with an opening in thebottom, with the floor F, closed at its rear and sides, and extendingnearly'to the front of the stove, and forming, in conjunction with thebottom of the stove, a passage or flue beneath the fire-chamber.extending from front to rear of the body of the stove, substantially asset forth.

2. The combination, in the stove-body A, of the diaphragm D, providedwith openings in the top and bottom, the former closed by means ofadjustable valve E of the floor 'F, closed at its rear and sides, andextending nearly to the front of the stove, and forming, in conjunctionwith the bottom of the stove, a passage or bottom flue, extending fromfront to rear of the stove, substantially as set forth.

3. The combination, with the stove-body A, of the floor F, said floorbeing closed except at the front, and forming, in connection with thebody of the stove, a flue passing lengthwise of the stove beneath thetire, and communicating at the rear, through the rear 'chamber, with thestove-pipe 11, substantially as set forth. 7

4.. In a stove, the floor F, arranged within the body and above thebottom thereof, having its rear and sides joined with the walls of thestove, and its front edge provided with a raised ledge or guard, f,substantially as set forth. l

5. The combination,in a wood-burnin g stove, having a bottom, F, closed,except at the front end a of a rear end flue,I, communicating with thefire-chamber at its rear end only, and terminating near said closed.floor, for the purpose set forth.

6. The combination, with the stove-body A, divided into a smoke-draftchamber and a tire-chamber, and provided with a floor or fire-bed, saidfire-chamber communicating with the smoke-flue through a free passagebeneath the bed from front to rear, of a draftpipe, I, arranged todescend into the interior of the stove at a point opposite to theentrance of the diving -flue, substantially as set forth.

7. The combination, in the stove-body A, divided into a smoke-draft anda fire chamber by a transverse partition, provided with openings in thetop and bottom, the upper one being closed with an adjustable valve, anda horizontal floor or fire-bed, forming, in conjunction with the bottomof the stove, a longitudinal flue beneath the fire-bed, communieating atthe forward end withthe fire-chamber, and at the rear with thesmoke-draft chamber, of a vertical draft-pipe, coinmuni-' eating at thetop with the outer air, closed with an adjustable slide or slides, andhaving its lower end descendingto a point within a short distance of thefire-bed,-substantially as set forth.

In testimony that I claim the foregoing I have hereunto signed my namebefore two subscribingwitnesses.
